[0042] Working principle: First, the user moves the scaffold to the desired working position through the self-locking universal wheel 1, fixes the universal wheel, and then pulls the cross bar 6 to pull the scaffold to the top. When the user pulls the scaffold, the limit block 204 at the bottom of the front side of the vertical pole 201 will move to the top with the vertical pole 201. When it moves to the top of the starting rod 3, the limit block 204 will pop out to the inner side of the limit hole 202 at the top of the front side of the starting rod 3 due to the pressure of the tension spring 203. The limit block 20 4 will be engaged with the limiting hole 202, thereby driving the vertical rod 201 to be engaged and fixed with the starting rod 3. Then the user pulls the end rod 4 and continues to move toward the top. When the end rod 4 moves upward, it will drive the limiting block 204 at the bottom of the front side of the end rod 4 to move. When it moves to the top of the vertical rod 201, it will pop out to the inner side of the limiting hole 202 at the top of the front side of the vertical rod 201 due to the pressure of the tension spring 203, and the limiting block 204 will be engaged with the limiting hole 202, thereby driving the end rod 4 to be engaged with the vertical rod 201. The rod 201 is clamped and fixed, and then the user pulls the bottom of the retractable ladder 7 to move the retractable ladder 7 downward. When the retractable ladder 7 moves downward, it will be fixed with the fixing block 16. Then the user moves the retractable ladder 7 to the top of the scaffold, places the load-bearing platform in the top support 5 for clamping and fixing. Finally, after the user finishes the work, the user moves the storage sleeve 14 to the top of the starting rod 3 to press the limit block 204 to the inner side of the limit hole 202, and the vertical rod 201 will be without support. Move downward and shrink to the inner side of the starting rod 3. After the vertical rod 201 is moved to the bottom, the movement of the vertical rod 201 drives the end rod 4 to move downward, and the limit block 204 at the bottom of the end rod 4 will move into the limit hole 202 at the top of the starting rod 3. Then the user continues to move the storage sleeve 14, and the end rod 4 will move downward and shrink to the inner side of the vertical rod 201 due to lack of support. Then the user takes out the load-bearing platform in the top support 5 and shrinks the retractable ladder 7 by squeezing the fixing block 16.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
